Directions

1.
Preheat oven to 475 degrees. Line two baking sheets with parchment paper; set aside.

2.
In a large bowl, whisk together flour, salt, superfine sugar, and baking powder. Make a well in the center and add butter. Using your fingers, work butter into flour mixture until a crumbly mixture is formed.

3.
In a medium bowl, whisk together 3 eggs and milk. Add milk mixture to flour mixture and stir to combine.

4.
Turn dough out onto a lightly floured work surface; knead lightly and shape into a round. Roll dough out until it is 1 inch thick. Using a 3-inch biscuit cutter, cut out scones and transfer to prepared baking sheets.

5.
In a small bowl, beat remaining egg and brush the top of each scone; sprinkle each with granulated sugar. Transfer baking sheets to oven and bake until golden brown and cooked through, 12 to 14 minutes. Transfer scones to a wire rack and let cool slightly before serving.

After a weekend of experimenting, here's what I found... Scottbutcher's recipe for a 6 scones had too much milk, ended up with a sticky mess for dough and dense scones. Made the scaled down version again using 1/2 cup of milk and then splashed in additional milk until dough barely clung together. Ended with perfectly flakey scones. I tried lowering temp to 450, but found after 12 minutes they hadn't browned at all. Made another batch at 475 and they came out perfect.

Scottbutcher's recipe for a 6 scones had too much milk, ended up with a sticky mess for dough and dense scones. Made the scaled down version again using 1/2 cup of milk and then splashed in additional milk until dough just barely clung together. This gave my scones that perfectly flakey texture.

I agree with shellbell14, the temp was too high. The first time I made it, I thought I would do the temp lower, because I didn't want to burn them. They didn't really poof up and rise like on the video, though. Second time I did 475 degrees for abt. 9 minutes. They burned a little, but didn't seem completely done. They seemed to rise a little more though. Did other peoples' do fine? It seems like a tricky recipe. Any help would be welcome.

In response to yellobutterfly. you can maker superfine sugar by putting regular sugar into a food processor or blender. Shellbell, the recipe calls for 1/4 plus 2 TBS of sugar. Did anyone else try this recipe?

I just made this recipe and was disappointed. First off, the recommended oven temp seemed way to high-the scones started to burn on the bottom after 7 minutes. Also, they seemed way more like a biscuit instead of a "scone". I added more sugar to the recipe as a little over 2Tbs. seemed way to shy given 6c. flour.

I don't have superfine, and I don't know what castor sugar is, will granulated white work? IF so, do I use the same amount, or less/more since it is a different sugar? On the show they showed a picture of these scones but they were a triangle shape and had a white glaze drizzled on top, was that a powdered sugar glaze, or is that devonshire cream also?
